WARREN N. HUTGHINSON, OF SOUTH BAY CITY, MICHIGAN, ASSIGNOR TOIMPROVEMENT IN CAR-COUPLINGS.

' Specification forming part of Letters Patent No. 179.1 16, dated June27, 1876 application filed November 23, 1875.

To all whom it may concern:

Be it known that 1, WARREN N. Huron- INsON, of South Bay City, in thecounty of Bay and State of Michigan, have invented an Improvement in(Jar-Couplings, of which the following is a specification:

The nature of my invention relates to an improvement in car-couplings,having for its object to so construct the draw-head as to automaticallyengage an entering link when presented edgewise to the jawthat is tosay,

turned axially a quarter-turn-and to hold the link in position forcoupling with another draw-head.

The invention consists in the peculiar construction of the draw-head andthe combination therewith of an internal buffer-spring, a leaf-springfor keeping the link behind ahook in the jaw, and an uncoupling device,as more fully hereinafter set forth.

Figure l is a perspective view. Fig. 2 is a cross-section at a; 01:.Fig. 3 is a sectional elevation of the draw-head, showing ,the linkhookand its butter-spring. Fig. 4 is a similar view of the other half of thedraw head, showing the link-spring and its yoke.

In the drawing, A representsa draw-head, havingalongitudinal verticaldivision through the center. One halt'has a cavity formed behind thebellnlouth to receive a rubber butfer-sprin g, B, having its centralportion cored out to increase the elasticity. In front of this bufferthere is a lateral hook, a, cast on the through a slot in the draw-head.

side of the jaw, with which hook the link 0 engages. Dis a leaf-spring,secured at its rear end to a recess in the other half of the draw-head.Its head I) or outer end is beveled to deflect the end of the linkinward. The link pushes it aside until past the hook at,

when the spring will throw it behind said hook.

The buffer-spring yields to the entering link, and then, pressing itagainst the hook, keeps it in any position in which it may be adjusted.

To uncouple, the spring D is provided with a yoke, 0, through which thelink passes. A short lever, E, is pivoted to the outside of thedraw-head, and is connected, by astaple, d, with the spring D, the saidstaple passing By pulling on the lever the spring D Will be retracted,and by the yoke 0 the link will be drawn from behind the lever, and thenbe pushed out by the buffer-spring. The shank of the drawbar may besolid, and only the outer part be divided, if preferred.

Y'Vhat I claim as my invention is- I The draw-bar A a, constructed asdescribed, the combinationtherewith ot' the buffer-sprin g B,leaf-spring G, yoke c, lever D, and staple d, in the manner and for thepurpose set forth.
